On Chris Williamson’s podcast, Stanford neuroscientist Robert Sapolsky breaks down 10 everyday behaviors—starting with replaying conversations in your head—that drive chronic stress and undermine sleep, mood, and nervous-system health. He pinpoints how these “normal” habits act as silent stressors most doctors overlook.

• Replaying past conversations retriggers real fight-or-flight responses, spiking cortisol and adrenaline as if the event were recurring.
• This repeated hormonal activation degrades sleep quality, worsens mood, and raises risk of headaches, gut issues, and immune suppression.
• Sapolsky recommends interrupting rumination by naming it ("I'm ruminating") and redirecting attention to a concrete task like reciting a poem or sketching.

Stanford neuroscientist Robert Sapolsky argues chronic stress is a hidden health killer. On Chris Williamson’s podcast he outlines ten common behaviors—starting with replaying conversations—that undermine sleep, mood, and nervous-system balance.

• This is a Twitter/X post teaser (only 1 of 10 promised behaviors is actually revealed: replaying conversations in your head)
• Claim: mentally rehashing conversations keeps the nervous system in fight-or-flight, delaying sleep onset and shortening REM
• Suggested fix: catch the loop early, name it, and redirect focus to something neutral like breathing
• No actual Sapolsky quotes or podcast details are included—just a promo summary referencing the Chris Williamson appearance

SleepFM is a novel foundation model developed to analyze polysomnography (PSG) recordings, facilitating accurate predictions of various health conditions based on sleep data. Trained on over 585,000 hours of sleep recordings, it demonstrates strong performance in predicting diseases such as dementia and heart failure, while also supporting standard sleep analysis tasks.

• SleepFM was trained on over 585,000 hours of polysomnography recordings, an unusually massive dataset for this domain.
• The model predicts diverse downstream conditions like dementia and heart failure directly from raw sleep data, not just standard sleep-stage/apnea metrics.
• It performs well on conventional sleep analysis tasks while also generalizing to disease prediction, suggesting a single foundation model can replace many task-specific ones.
